NOTE: After the control gate has been reset, the
conveyor must be run until the adjusted material
flow is past the discharge point. Disregard the
material released during this operation and re-
zero the meter.
After calibrating using weight it is recommended
that the yield of each mix be verified by batching
concrete into a yield box (container of known
volume) and comparing the results with that
displayed by the meter. Small adjustments in the
gate setting may be necessary to produce the
desired yield. A yield correction factor can be
entered into the computer that will adjust the
gate heights accordingly in the mix entry screen
(see Control System manual) or the adjusted
heights can be entered and saved manually.
Fibre Feeder Calibration
NOTE: There is a flow rate chart inside the front
cover of the fibre feeder for reference
